Rainfall Influence Solar Panel Performance: Research

Washington, 25 Feb (ONA) --- Research led by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) revealed that rainfall alone isn't sufficient to cleanse solar panels of pollen, impacting their power generation capabilities.

The study, based on data from five solar fields in North Carolina in the United States of America, highlights that soiling, caused by dust, dirt, and pollen, significantly reduces solar performance during peak pollen seasons, decreasing output by up to 15%.

Mechanical brushing, however, enhances performance by 5% to 11%.

NREL's Matthew Muller emphasized the necessity for regular panel cleaning to maintain optimal performance.

While homeowners may manage cleaning, larger installations require additional labor, potentially causing up to 10% annual production loss.

Soiling levels vary by location and climate, with dusty areas and regions abundant in plant life experiencing more significant issues.
